Hi VK, Hope I can rejuvenate the OP and continue it. I am interested in three of the topics mentioned in your OP and I am not clear about the way we take up those issues in six sigma. I try to put my thoughts here so that you can help me correct where ever I am missing something. The first one is improving CSI. I can't think beyond this point that improving customer ratings is a logical process and those points where customer is unsatisfied is clearly visible without having to go through any data analysis. As far as weightages are concerned, it is company's philosophy as to what is more important and what is less. Improving forecasting efficiency is clear to me, as long as the data is accurate. Even thought the data is accurate, there are always chances for a marketing guy to complain that there could have been more sales if he had more product in their hands. If we only focus on the data that is available to us, we may miss link to the potential possibility. I am totally blank on using six sigma for improving channel effectiveness beyond conventional means. I would appreciate if I get any leads in this regard or references to existing projects. Regards,
